The top of the rotating column 802 is fixedly connected to the support frame 2. The bottom of the control motor 805 is fixedly connected to the support plate 803. The output end of the control motor 805 passes through the support plate 803 and extends to the outside of the support plate 803, where it is fixedly connected to the drive gear 804. The drive gear 804 meshes with the adjusting gear 801 on the side closest to the adjusting gear 801.

[0036] The above scheme is adopted as follows: by setting the adjusting gear 801, the rotating column 802 and the support plate 803 can be driven to rotate synchronously; by setting the control motor 805, the driving gear 804 can be driven to rotate; by setting the driving gear 804, the adjusting gear 801 can be driven to rotate; by setting the rotating column 802, the support frame 2, the support plate 803 and the machine tool spindle 1 can be driven to rotate synchronously; by setting the support plate 803, the limiting rod 806 can be driven to rotate synchronously; by setting the limiting rod 806 and the receiving groove 807, the moving rod 901 can be supported and limited; and the moving rod 901, the support frame 2, the positioning rack 903 and the positioning plate 904 can be driven to rotate synchronously; by setting the limiting block 808, the lifting screw 1002 can be supported and limited.

[0039] During use, depending on the length of the machine tool spindle 1 to be inspected, place the support block 3 at a suitable position above the positioning groove 4 on the top of the support frame 2. Then, align the positioning pin 5 at the bottom of the support block 3 with the positioning groove 4 and place it inside the cavity of the positioning groove 4. After placement, place the machine tool spindle 1 on top of the support block 3. After the machine tool spindle 1 is placed, move the limit block 907 upward and squeeze the return spring 906. When the limit block 907 and the positioning rack 903 are no longer in contact, the return spring 906 will be released. Positioning plate 904 is moved to a suitable position at the top of machine tool spindle 1. Then, the limit block 907 is released. The force released after the return spring 906 is squeezed pushes the limit block 907 to move in the opposite direction and reset, fixing positioning plate 904. After positioning plate 904 is adjusted, the control handle 1001 is rotated, driving the lifting screw 1002 to rotate. The lifting screw 1002 drives the lifting component 1003 and positioning frame 902 to move downward synchronously. The positioning frame 902 drives the positioning rack 903 and positioning plate 90 4. Move downwards synchronously. When the positioning plate 904 contacts the machine tool spindle 1, stop the rotating shaft control handle 1001 to complete the positioning. During maintenance, when it is necessary to adjust the direction of the machine tool spindle 1, start the control motor 805 to drive the drive gear 804 to rotate. The drive gear 804 drives the adjusting gear 801 to rotate on the top of the support plate 7. The adjusting gear 801 drives the rotating column 802 and the support plate 803 to rotate synchronously. The rotating column 802 and the support plate 803 drive the support frame 2 and the limit rod 8. 06 and the moving rod 901 rotate around the support plate 7. The support frame 2 drives the rotating wheel 6, the support block 3 and the machine tool spindle 1 to rotate synchronously. At the same time, the limit rod 806 and the moving rod 901 drive the positioning frame 902 and the positioning rack 903 to rotate synchronously. The positioning rack 903 drives the positioning plate 904 to rotate synchronously, so that the positioning plate 904 rotates synchronously with the machine tool spindle 1 while the machine tool spindle 1 rotates. When the machine tool spindle 1 reaches the appropriate angle, the control motor 805 is stopped to complete the adjustment.

[0040] In summary, this machine tool maintenance rack, through the coordinated use of the adjustment device 8, positioning device 9, and lifting assembly 10, solves the problem that existing machine tool spindles, during maintenance, mostly involve placing the machine tool spindle directly on top of two support blocks, failing to provide support and positioning for different spindle lengths. Furthermore, during maintenance, when different positions of the machine tool spindle need to be inspected, the user often needs to move to the corresponding position, increasing the user's workload.
